A lottery has 46 numbers. How many ways can six numbers be drawn if they numbers are not repeated?

7 ways

Step-by-step explanation:

You start off with 46 numbers

1.  46-6=40

2. 40-6=34

3. 34-6= 28

4. 28-6= 22

5. 22-6= 16

6. 16-6= 10

7. 10-6=4

We can not do anymore because there is not enough numbers left.

step-by-step explanation:

a and d

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
